A race-condition flaw was discovered in openstack-neutron before 7.2.0-12.1, 8.x before 8.3.0-11.1, 9.x before 9.3.1-2.1, and 10.x before 10.0.2-1.1, where, following a minor overcloud update, neutron security groups were disabled. Specifically, the following were reset to 0: net.bridge.bridge-nf-call-ip6tables and net.bridge.bridge-nf-call-iptables. The race was only triggered by an update, at which point an attacker could access exposed tenant VMs and network resources.

Quick emulator(Qemu) built with the USB xHCI controller emulator support is vulnerable to an infinite loop issue. It could occur while processing control transfer descriptors' sequence in xhcikickepctx.

A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS.

Beth Lancaster and Brandon Sawyers from Virginia Tech reported a vulnerability in Horizon. By injecting Angularjs template in dashboard forms, such as image's description, an authenticated user may trigger a cross-site-scripting vulnerability when another user browses the affected pages. It may result in potential assets theft like user access credentials. All Horizon setups are affected.
